CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 312,181, dated February10, 1885. Application filed July 21, 1884. (No model.)

To all whom it may concern.-

Be it known that we, J. GEORGE BRILL and EDWARD H. ZITZMAN, citizens ofthe United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Oar-Axle Boxes, of which the following isaspecification, reference being had therein to the accompanyingdrawings, wherein Figure l is a vertical longitudinal section of anaxle-box embodying our improvements. Fig. 2 is a cross-section on line 11 of Fig. 1. Fig. 3 is an elevation of the followers for thedust-excluder or packing at rear end of the box, showing thespringmechanism for obtaining the automatic movement of the followersfor taking up the wear of the wood or packing-plates, the latter notbeing indicated. Fig. 4 is a broken top view of one of the followers.Fig. 5 is a side or edge elevation of a follower. Fig.6 is a brokenhorizontal section through the oil-conduit. Fig. 7 is atransversesection of a paddle or oil-torcing wheel having adjustable blades orpaddles. Fig. 8 is a rear elevation of axle-box. Fig. 9 is a plan,partly sectional, ofsame; and Fig. 10 is a broken elevation of one ofthe wooden or packing plates for the d ust-excluder at rear end of box.

Our'inveniion has relation to improvements in aXle-boXes, havingparticular reference to devices for oiling the axle-journal and itsbearing, to shields and packing for excluding dust and dirt andpreventing leakage of oil from the axle-box, and to the formation of theaxle and the box; and it has for its objects, first, to dispense withthe usual waste in the oil-well of the axle-box and substitute therefora force or paddle wheel mechanism and appropriate oil conductors orconveyers, whereby the oil is mechanically raised from the box oil-wellto the top of the journal brass or hearing, and through which said oilfinds its way to the axlejournal; second, to provide an axle having areduced portion or diameter in rear of the journal, and separated fromthe latter by a collar, said reduced portion having its location in therear wall of the box, and serving to prevent leakage from the box of anysurplus oil supplied to the axle-bearing; third, to provide an axle-boxwith an open top and a double chambered or recessed rear wall, each ofwhich has a dust-excluder packing; and, finally, to provide adust-shield so constructed that it antomatically takes up its wear. Ourinvention accordingly consists of the combination, construction, andarrangement of parts, as hereinafter described and claimed.

In the drawings, A represents an axle-box, which may be of any suitableconstruction and design and be provided with any desired form of lid andusual appurtenances; but we prefer to make it with an open top, a, whichis closed by a cap or cover, B, extending the length and width of thebox, as shown, or otherwise, as desired. Both the cap B and box A areformed with aligning vertical openings 0, through which pass bolts C, asmore plainly shown in Fig. 9, for'securing said parts, or firmly boltingthem together to form a tight joint between them, their meeting surfacesor edges being finished, if desired, or provided with a gasket or otherpacking. On the bottom and sides of box A, or otherwise located, areguides or slotted brackets d,which receive sliding or vertically-movingbearing-blocks d, resting upon springs or other elastic supports, (1",the tendency of which is to move the blocks d upwardly, or away from thefloor or bottom of box A.

In blocks dis journaled a shaft, (Z on which is mounted awinged orpaddle wheel, D, having end disks or collars, D D, the periphery ofwhich extends beyond the outer edges, f, of the paddles, wings, orblades F. The shaft (1 and paddlewheel I) may be separately made, asshown, and aresuitably connected; or they and the blades F may all beformed integral. Each of the blades F may bein one piece of metal orother material, as indicated in Fig. 2, or be composed of sections f andf the'latter being radially adjustable upon the former, as representedin Fig. 7, and are made of leather, rubber, or other flexible material.

Upon the inner walls of the sides of box A, and at its forward end, arebrackets g, having upper open end slots, into which passes a transversecheck orguard bar, G, for preventing undue end movement of axle H.

On the inner wall of one of the sides of box A are dovetail or othergrooved tenons or bolts 0, which pass through elongated openguide-bars,i, which receive and firmly support a removable conduit or pipe, I,which extends upwardly along one side of the axle and is bifurcated ator near its upper end to provide two outlets, it", bent at i andprojecting into chambers or recesses 75 of brass or hearing K. The mouthor inlet 13 of conduit I is located opposite to and below the lower halfof the paddle-wheel D, as shown more plainlyin Fig. 2. The brass K has acentral segmental or other configured transverse slot, 76, into whichenters a correspondingly shaped and located rib, b, on cap B, to form akey for holding the brass in position and for preventing longitudinalmovement of same.

From the brass chambers or recesses lead vertical or radial openings7t", for conducting the oil supplied to said chambers to theaxlejournal. The operation of oiling the latteris as follows: Thesprings d hold the disks D of the paddle-wheel D in close contact withthe journal h, so that as the latter revolves it communicates a rotarymotion to the paddlewheel D, whose blades sweep or force the oil in wella into and up the conduit I, and thence into the brasschambers 7r, fromwhich it flows by way of openings 76 to journal h. The wear of the disksD is automatically taken up by the springs (1 The axle-box A has atriple rear wall, A A A inclosing vertical chambers A* and A, of whichthe former has an open bottom, a, and the latter an open top, u Thesewalls are provided with the usual oval openings for the passage of theaxle H, which has that portion of its length which is located in chamberA reduced in diameter, as shown at if, so as to provide a collar, h,between the journal h and the reduced portion 71. for preventing surplusoil on the bearing or journal traveling back of the latter and leakingfrom the axle-box. To further avoid the last-named result, or to provideadditional means for preventing oil-leakage from the box, and also toexclude dust therefrom, we place a guard or shield, L, in chamber A.This guard is composed of two oppositely-arranged tapering orwedge-shaped followers, M M, having central openings or slots, on, forthe passage of axle H, and flanges m,with ribs or tenons m at one oftheir edges or ends, as more plainly shown .in Fig. 3.

Upon or attached to each follower is a wood or other suitable plate orpacking, N, having central axle-openings, a, as illustrated. The outsidesurfaces, n, of these plates are provided with grooves a", into whichare fitted gum or other gasketsmiwhich impinge against the opposite oradjacent transverse walls of chamber A, as indicated in Fig. 1, and forma tight joint therewith. The followers M are so arranged that theycontact or impinge upon one another between the wooden plates N to forma double wedge, (see Figs. 1 and 3,) the ribs m of the followersentering plows or recesses n in the plates N. Said followers are looselysecured together by ings 0 in their flanges m. See Figs. 4 and 9.) Thesebolts 0 project below the flange m of the lower follower, M, and areprovided with expanding spiral or other springs, 0", a connecting springseat or plate, 0", and fastening and adjusting nuts 0. Each plate N iskept in position upon its respective follower, so as to move therewith,by the rib m of the follower entering the plow or recess a of the plate.The expansive action of the springs 0 against the flange m of the lowerfollower and the spring-plate 0 tends to exert a downward pressure uponthe upper follower and its plate N, and upward pressure upon the lowerfollower and its attached plate, or tends to move or slide the followersupon one another, and, as they are tapering or wedge shape, any verticalmovement of the followers moves the plates N N laterally farther apartfrom one another, orincreases the thickness ofthe guard or shield L inthe direction of the axis of the axle to always automatically keep thegaskets n of plates N in close contact with the contiguous walls ofchamber A and edges in n of the central openings of said plates inimpingement with axle H, or its reduced portion h", as shown, andthereby form a dust-tightjoint between said parts, the wear of which isal' ways automatically tak en up by the expansive force of the springs0". provides a dust-excluder, but it also prevents leakage from box A ofany oil that may escape from the oil'well a or the journal bearing tothe reduced portion of the latter.

In chamber A is placed a secondary dustexcluding plate or shield, P,composed of a single piece of vulcanite,or of the usual material nowemployed for dust-shields for caraxle boxes. If desired, however, saidshield P and its chamber A maybe dispensed with. The cap B is providedwith an extension, B, for covering the top of chamber A; but wheneverdeemed necessary such extension need not be used, in which case thechamber A will then be open at both its top and bottom.

The box A is shown provided with side supports, for the usual or otherbearingsprings, and has openings (1 for the passage of the bolts whichhold the bearing-springs and secure the axle-box to the car in the usualor well-known manner; but it is obvious that these spring-seats Q. aredispensed with when box A is placed in and has a vertical movement inthe usual or other forms of pedestals.

If desired, oil-conduits I may be used on both sides of the axlebox, sothat oil will always be supplied to the brass K, in whatever directionthe axle may be rotated, or to provide for the lubrication of theaxle-journal during a backward movement of a train or car.

If desired, the paddles of wheel D may be perforated to prevent undueresistance being offered to their passage or rotation through the oil inwell or box A, and these perforations are plainly shown in Fig. 1.

It will be noted from the foregoing that the The shield L not onlyaxle-journal is mechanically lubricated by the forcing of oil to itsbearing, such forcing being effected by means of a paddle-wheel rotatedby the axle; that a sectional follower dustshield havingautomaticallyacting mechanism for taking up the wear of its axlecontact-surfaces is provided for excluding dust and preventing leakageof oil from the axle-box, and that the latter has an open top extendingfrom end to end, whereby all the fixtures for the interior ofthe box maybeeasily placed therein and removed therefrom for repairs, renewal,orotherwise.
